If you have followed this blog at all, you might remember that people from Medellín and the surrounding area are called Paisas (and are great business people), and that people from Pasto – Pastusos, in the south of Colombia, are the traditional butt of regionalist jokes.

So, one day someone from Pasto is trying to sell a cow.

I’ll sell it for you, says the Paisa.

OK, says the Pastuso, sell it for a million pesos and I’ll give you 200,000.

So the Paisa gets started: Cow for sale! She doesn’t produce milk, she produces yoghurt. She doesn’t produce milk, she produces butter. Great cow for sale!

Wait a minute, says the Pastuso, if she can do all that, I don’t want to sell her!
